Compute Beam Deflection - easy money! -- 2

All data is attached. I need a complete solution, nicely written, step by step, in Latex. If you can't write Latex, you can submit hand-written paper too, but only if it's readable and clear. So, again, we need BEAM DEFLECTION here. Tell me whether you know the formula or not.

Check the files!

I can pay $20, I need it in 12 hours as it's simple for anyone who knows how to calculate!
